https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D188899 --- Comment #14 from commit-hook@freebsd.org --- A commit references this bug: Author: marius Date: Sun Dec 27 15:18:01 UTC 2015 New revision: 292775 URL: https://svnweb.freebsd.org/changeset/base/292775 Log: MFC: r286785, r291088, r291120 - Reformat x86 bounce buffer synchronization code to reduce indentation. No functional change. - Avoid a NULL pointer dereference in bounce_bus_dmamap_sync() when the map has been created via bounce_bus_dmamem_alloc(). Even for coherent DMA - which bus_dmamem_alloc(9) typically is used for -, calling of bus_dmamap_sync(9) isn't optional. [1] - Avoid a NULL pointer dereference in bounce_bus_dmamap_unload() when the map has been created via bounce_bus_dmamem_alloc(). In that case bus_dmamap_unload(9) typically isn't called during normal operation but still should be during detach, cleanup from failed attach etc. [2] PR: 188899 (non-original problem) [1] Submitted by: yongari [2] Changes: _U stable/10/ stable/10/sys/x86/x86/busdma_bounce.c --=20 You are receiving this mail because: You are the assignee for the bug.=
